ON MEXICO ISSUES

  • The full Supreme Court of Justice of the Nation (SCJN) revoked an injunction granted to a private individual against the reforms to the Mining Law regarding mining and water concessions promoted by former President Andrés Manuel López Obrador (AMLO). By seven votes in favor and two against, the justices denied the judicial protection requested by the individual because the new concession applications that were in process were dismissed without further proceedings after the reforms came into force in May 2023. During the debate, Hugo Aguilar, president of the SCJN, affirmed that the sovereignty of the State must prevail at all times and that under no circumstances does anyone who submits a mining concession application already have an acquired right, simply by submitting it. (Editor´s Note: The SCJN´s decision is a bad sign, not only for the mining industry but for the entire country, because no respect for the non-retroactivity of laws has been demonstrated, and that’s a basic principle for the Rule of Law).
  • GR Silver Mining Ltd., and Kingsmen Resources Inc., reported the best drilling intercepts in Mexico on the fourth week of September, 2025. Details are shown in the table below:

ON EXPLORATION

  • Riverside Resources Inc., and Questcorp Mining Inc., informed that are conducting a drilling program at the Union project in Sonora, targeting five mineral zones. Currently, three targets are actively being drilled, focusing on historic mining areas and new potential zones like Famosa, which shows signs of gold mineralization. The program is progressing on schedule and budget, with promising signs of gold-bearing mineralization, especially in areas with significant quartzite and structural features. The first hole was drilled southeast beneath historic workings, and two more holes were drilled at the El Cobre mine area and the North Union Mine area, perpendicular to stratigraphy and toward interpreted feeder zones along pre-mineral fault structures, primarily within the Clemente Formation. Core samples have been sent to the lab and assays are pending.  Goal of this exploration campaign is to define mineralization controls, refine exploration models, conduct an additional induced polarization (IP) survey and evaluate sulfide zones, with ongoing geological interpretation and assay results guiding their next steps.
  • Colibri Resources Corporation reported that it has engaged TerraEye to advance and enhance exploration at the EP Gold Project in Sonora using a mix of multispectral satellite imagery, geospatial data, AI and data integration like magnetics, gravity, and geochemical database to uncover promising gold targets even hidden by dense vegetation. The goal is to produce a ranked list of exploration targets with detailed maps and reports to accelerate discovery, reduce exploration risks, and optimize field work and drilling efforts, with a planned program in 2025 to expand target identification beyond the initial three drill-tested zones.
  • Kingsmen Resources Inc., announced initial results from its Las Coloradas project in Chihuahua. Hole LC-25-010 intersected 1,028 g/t AgEq over 1.45m (455 g/t Ag approx), including 1,742g/t Ag over 0.7m (770 g/t Ag approx) and a broader zone of 138 g/t AgEq over 13.35m, confirming potential for high-grade, shallow mineralization near historic ASARCO mining areas. The mineralization includes massive sulfides with sphalerite, galena, arsenopyrite, and pyrrhotite, and shows strong pathfinder elements like antimony, bismuth, and indium, indicating a large, underexplored system. The project covers a historic district with multiple untested structures, and only a small part has been explored. Kingsmen plans to analyze additional drill holes and continues to assess the district’s extensive mineral potential. The company emphasizes the significance of these results in confirming the presence of high-grade silver mineralization and the potential for further discoveries in this prolific mining district.
  • Pinnacle Silver and Gold Corp., discovered a new vein called El Capulin at its Potrero project in Durango that along with the surface sampling conducted above the Pinos Cuates and Dos de Mayo mines reinforces the idea that a robust low-sulphidation epithermal vein system with significant gold-silver mineralization has been identified at the property. Surface sampling has extended the high-grade-gold and silver mineralization over a vertical distance of up to 80m above the Los Cuates and Dos de Mayo mines, with grades of up to 2,280 g/t Ag and 1,444 g/t Ag, suggesting vertical zonation with silver increasing upwards. Also, sampling on the newly discovered El Capulin vein, with a strike length of 375m, returned values up to 6.27 g/t Au and 99 g/t Ag. This vein lies parallel to Dos de Mayo, 200m away. In addition, mapping at the La Dura mine could extend the Dos de Mayo vein strike length to 500m, with the vein traced for 1,600m overall. All these results add a lot of potential to the El Potrero property.

ON MINING

  • Guanajuato Silver Company Ltd., made significant upgrades to its mining fleet at its El Cubo and Valenciana mines in Guanajuato, including the delivery of three new low-profile trucks, three scooptrams, and three ordered “Torino” haulage trucks to arrive later. These modern vehicles are designed for enhanced safety, stability, and efficiency underground, aiming to improve operational reliability, increase production, and optimize fleet utilization. The company emphasized that these investments are critical to supporting long-term growth and operational success.

ON FINANCING

  • Masivo Silver Corp., increased its previously announced non-brokered private placement due to strong investor demand from 16,666,667 to 33,333,334 units for gross proceeds from CAD $1M to CAD $2M. The offering will be priced at CAD $0.06 per unit (Cerro Colorado project, Sonora).
  • Silver Storm Mining Ltd., closed its previously announced bought deal private placement of 55,065,000 units at a price of CAD $0.25 for gross proceeds of CAD $13,766,250. The company plans to use the net proceeds to advance the restart of the La Parrilla mine in Durango, as well as for general corporate purposes and working capital.
  • Sandstorm Gold Royalties announced that proxy advisory firms recommended Sandstorm shareholders vote in favor of the proposed arrangement with Royal Gold Inc, scheduled for October 9, 2025. Under the deal, Sandstorm shareholders will receive 0.0625 shares of Royal Gold for each Sandstorm share. The Board of Directors of Sandstorm unanimously supports the vote for the arrangement resolution.
  • Aztec Minerals Corp., announced a bought deal private placement offering of 21,300,000 common shares of the company at a price of CAD $0.235 per offered share for gross proceeds of CAD $5M, but later on it announce an upsize of the bought deal to 37,020,000 common shares at a price of CAD $0.235 for gross proceeds of CAD $8,699,700. Part of the gross proceeds will be used to conduct exploration work at the Cervantes project in Sonora, as well as for general working capital purposes.
  • Zacatecas Silver Corp., closed the first tranche of its previously announced private placement for gross proceeds of CAD $2,306,960 by issuing a total of 38,449,335 units at a price of CAD $0.06 per unit. The company plans to use the net proceeds to fund a drilling campaign on its Zacatecas Silver project in Zacatecas.
  • Oroco Resource Corp., announced a non-brokered private placement of up to 18,000,000 units at a price of USD $0.20 for gross proceeds of up to USD $3.6M. Oroco will use the net proceeds for the advancement of its Santo Tomas project in Sinaloa, as well as for working capital and other general corporate purposes.
  • Questcorp Mining Inc., informed that it will offer up to 17,500,000 units at a price of CAD $0.20 per unit in a non-brokered private placement for gross proceeds of up to CAD $3.5M. The company plans to use part of the gross proceeds for advancement of ongoing exploration and drill work at the La Union Gold and Silver Project in Sonora, and for general working capital purposes.
  • Kenadyr Metals Corp., closed the second tranche of its previously announced non-brokered private placement of 1,959,665 subscription receipts of Kenadyr at a price of CAD $0.37 per subscription receipt for gross proceeds of CAD $734,874.38.

The company will used the proceeds to fund payment obligations and exploration expenditures relating to the Adelita Project in Sonora, and for general working capital purposes.

ON RESOURCES AND DEVELOPMENT

  • Guanajuato Silver Company Ltd., made significant upgrades to its mining fleet at its El Cubo and Valenciana mines in Guanajuato, including the delivery of three new low-profile trucks, three scooptrams, and three ordered “Torino” haulage trucks to arrive later. These modern vehicles are designed for enhanced safety, stability, and efficiency underground, aiming to improve operational reliability, increase production, and optimize fleet utilization. The company emphasized that these investments are critical to supporting long-term growth and operational success.
  • GR Silver Mining Ltd., released drilling results from the San Marcial area at its Plomosas project in Sinaloa. Drill hole SMS25-10A intersected two distinct mineralized zones in the Parallel Breccia Target, including374 g/t Ag over 9m with high-grade intervals of 1,542 g/t Ag, 1.4% Cu, and 0.62% W over 1m, and  1.44 g/t Au over 33m, with a high-grade interval of 32.1 g/t Au over 1.2m. This drill hole is the farthest southeast drilled in the Parallel Breccia Target, confirming continuity of the mineralized structure over at least 500m from the Resource Area and supporting exploration models linking silver mineralization to a porphyry-style geological setting. The presence of high-grade Ag-Au zones, along with anomalous Cu and W grades, revealed intense high-temperature alteration minerals and epithermal-style quartz-calcite stockwork zones, suggesting proximity to a porphyry-related system and providing valuable vectoring tools for future exploration and strong potential for further resource expansion at San Marcial, particularly in the NE-SW structural trend.
